Dirofilaria immitis infection in dogs: Cardiopulmonary biomarker levels

Veterinary Parasitology. Volume 176, Issue 4, 22 March 2011, Pages 313-316
Carretón, E., Corbera, J.A., Juste, M.C., Morchón, R., Simón, F., Montoya-Alonso, J.A.

Abstract

Cardiopulmonary biomarkers are biological parameters that can be objectively measured and quantified as indicators of pathogenic processes (heartworm disease) or as indicators of response to therapeutic intervention. To determine levels of cardiopulmonary biomarkers in canine dirofilariasis, measurements of cardiac troponin T, cardiac troponin I, myoglobin, and D-dimer concentrations were performed for dogs with and without evidence of adult heartworm infection. The results showed that levels of cardiac troponin T were undetectable in all dogs studied while levels of cardiac troponin I were higher in dogs infected with Dirofilaria immitis. In healthy dogs, levels of myoglobin and D-dimer were below detection limits of the instrument and were significantly higher in heartworm-infected dogs, notably in microfilaremic dogs. The results suggest the possibility of using troponin I and myoglobin as markers for cardiac damage and the D-dimer as a supportive tool for a diagnosis of pulmonary thromboembolism in dogs with cardiopulmonary dirofilariasis.

Current prevalence of Dirofilaria immitis in dogs, cats and humans from the island of Gran Canaria, Spain.

Montoya-Alonso, J.A. , Carretón, E., Corbera, J.A., Juste, M.C., Mellado, I., Morchón, R.b, Simón, F.

Abstract

The island of Gran Canaria is a hyperendemic area for canine dirofilariasis. The aim of the present study was to provide data on Dirofilaria immitis in dogs, cats, and humans on this island in 2010. The data confirms the prevalence in the overall canine population (19%), with a considerably higher prevalence (43%) in the autochthonous breed of Canarian Warren hound. The prevalence in the feline population (33%) is higher than that of the canine population, and the existence of specific D. immitis antibodies in the inhabitants of the island of Gran Canaria (12%) is confirmed. In both cats and humans, the prevalence, according to the different climate areas on the island, is related to the prevalence of D. immitis in dogs in the same area, which shows the key epidemiological role played by the canine host with regard to the transmission to other hosts of D. immitis.

Testicular Neoplasms (Interstitial and Sertoli Cell Tumours) in a Domestic Ferret (Mustela putorius furo) (Article)

Reproduction in Domestic Animals
Volume 46, Issue 1, February 2011, Pages 177-180
Batista-Arteaga, M. , Suárez-Bonnet, A., Santana, M., Niño, T., Reyes, R., Alamo, D.

Abstract

Contents: Unilateral testicular enlargement was detected in a 5-years-old domestic ferret during a routine sterilization. The right testicle showed two different types of proliferative lesions: (i) round nodules, well demarcated, showing a soft yellow tissue; (ii) white nodules, firm, with irregular-shaped invaginations. Microscopically, the neoplastic proliferations were identified as an interstitial neoplasm and Sertoli cell tumour, respectively. The left testicle was small and showed intense testicular atrophy. Clinical evaluation of the ferret did not show any other apparent pathological processes. This study is the first case reporting the concomitant occurrence of a Sertoli cells tumour and an interstitial cell tumour in a domestic ferret.

Double-layer mesh hernioplasty for repairing umbilical hernias in 10 goats

Turkish Journal of Veterinary and Animal Sciences
Volume 35, Issue 2, 2011, Pages 131-135
Vilar, J.M., Corbera, J.A., Spinella, G.

Abstract

Umbilical hernias in goats are uncommon and can vary in their etiology and management. Hernioplasty can be done by closing the abdominal wall with a horizontal mattress pattern using absorbable sutures. However, larger defects (hernial ring size >3 cm) generally require the use of prosthetic materials that allow for a tension-free repair. In this study, 10 young female goats with umbilical hernias and hernial ring sizes ranging from 7-10 cm in width were treated using a double-layer polypropylene mesh. An ultrasonographic examination was performed to assess healing and connective tissue production.

Epidemiological survey of canine heartworm disease on the island of Gran Canaria (Canary Islands – Spain) between 2000 and 2008.

Veterinary Parasitology. Volume 173, Issue 1-2, October 2010, Pages 165-168
Montoya-Alonso, J.A., Carretón, E., Juste, M.C., Mellado, I., Morchón, R., Simón, F.

Abstract

Canine cardiopulmonary dirofilariosis caused by Dirofilaria immitis is endemic on the island of Gran Canaria. Epidemiological surveys have shown differences in the prevalence of heartworm disease in the canine population of the island between 1989 and 1998. The aim of the present study was to follow-up the prevalence of D. immitis in both the canine population as a whole and the Canarian Warren Hound population on Gran Canaria between 2000 and 2008. Prevalences observed were always significantly higher in the Canarian Warren Hound population than in the entire canine population. A significant decrease in the prevalence (from 30.19% to 19.36%) in the whole population was observed. In the Canarian Warren Hound the prevalence decreased slightly between 2000 and 2007 (40.42-34.65%), rising in 2008 to values higher than those observed at the beginning of follow-up study (41.6%). These changes are mainly attributed to lack of preventive chemotherapy and the prolonged exposure of the Canarian Warren Hound to mosquito bites. As this breed can act as a natural reservoir in Gran Canaria, regular surveillance is needed to detect changes in the epidemiological picture on this island.

Canine dirofilariosis caused by Dirofilaria immitis is a risk factor for the human population on the island of Gran Canaria, Canary Islands, Spain

Parasitology Research. Volume 107, Issue 5, 2010, Pages 1265-1269
Montoya-Alonso, J.A., Mellado, I., Carretón, E., Cabrera-Pedrero, E.D., Morchón, R., Simón, F.

Abstract

The aim of the present study was compare the prevalence of D. immitis in dogs and seroprevalence in humans of Gran Canaria (Canary Islands, Spain) taking into consideration the four isoclimatic areas of the island. A close relationship between the prevalence of Dirofilaria immitis in dogs and the seroprevalence in humans, in each isoclimatic area, was observed. The highest seroprevalence of infection in both canine and human hosts were found in a strip of mid-range altitude with 25.47% and 30.4% in dogs and 25.66% and 29.73% in humans, respectively. The coastal zone and the highest part of the island have prevalences significantly lower. These results demonstrate that the risk of infection by D. immitis in the human population in each area is tied to the prevalence in the canine population. Physicians should be alerted to the possibility of finding cases of human pulmonary dirofilariosis amongst the inhabitants of the island.

Dystocia and paraparesis associated with intra-pelvic space-restricting hematoma in a Spanish ibex (Capra pyrenaica hispanica)

Journal of Applied Animal Research
Volume 37, Issue 1, 2010, Pages 89-91
Vilar, J.M. , Corbera, J.A., Ramírez, G.A.

Abstract

This report presents a case of dystocia and mummification of a. co-twin fetus in a nine-year-old pregnant Spanish ibex (Capra pyrenaica hispanica) that was a direct result of capture procedures. The anesthetic dart penetrated the left perivulvar region, causing α large intra-pelvic space-restricting hematoma. Subsequently, the doe developed bilateral hindlimb paresis and marked vaginal prolapse. On cesarean section one of the fetuses was dead and exhibited features of initial maceration. The second fetus was weak, but survived and appeared normal. The doe recovered well from the anesthesia, but after 48 h displayed lethargy, ataxia, disorientation and extreme weakness and it was deemed appropriate to euthanize the animal. The postmortem examination revealed lesions suggestive of pregnancy toxemia. Trauma in pregnant wild goats should raise the clinical suspicion of fetal death and dictate further observation; in a. twin pregnancy, the appearance of a single fetal death should be investigated.
